Hello Neblix! Thank you so much for replying me! I'm sorry it took me so long to reply due to the holidays.
When I started learning how to use DAWs I used to use FL Studio, now I use Cubase. The only reason I've changed is that FL Studio used to crash A LOT! Not very good at using the computer memory. I can do so much more on that department with the Cubase. Given that Cubase doesn't crash with me... But I did prefer FL Studio, the notation system I find better and I didn't have this issue that I am having. All VST plugins were easier to control, if I remember correctly.
Anyway, I have tried all plugins I could find for free out there to run my soundfonts, but the sound quality in most of them is quite deplorable when running the same soundfonts! TX16Wx, I fear, is the best sounding one. And I really want to figure out how its automation track works.
For other VSTs and for people with a similar problem I found out this method, by try and error:
1. First right click in this general area to make this list appear:
2. Then click on Switch to Generic Editor
3. Your VST will change into this Cubase-like layout.
4. Say you want to control the pan on the track; then you right click on the that bar to make Show "whatever" Automation Track
5. Finally under the VST Instruments Folder; under your VST folder, in this case Toad Nes drum, you'll find a new "whatever" in this case "pan" track.
Sadly with TX16Wx, the one VST I'm needing, I get this list for parameters but they don't have the Show Automation Track option.
